Privacy Policy, End User License, and Warranty Agreement

Privacy Policy

This document applies to PRAELUDIUM & CODEX mobile apps, developed by Sealed Book Ltd. We’ve tried to keep text simple, so we hope you will take the time to read it carefully.

Personal information

We made PRAELUDIUM & CODEX with your privacy in mind, so we do not automatically collect any personally identifiable information about you. In other words, we do not collect at any time information such as your names, date of birth, addresses, bank details, phone numbers, or precise geographic location. Solely at your discretion, you can choose to subscribe to our newsletter, and you may and can opt-out at any time by following the unsubscribe link or the instructions provided with any email we send. The applications require network permissions in order to download and show advertising media like videos, images, and text.

Usage analytics

We would like to make PRAELUDIUM & CODEX and all our products more useful for you, so there may have Firebase Analytics and/or similar platforms integrated. Those programs collect user behavior information in an anonymous form and transmit it to Google’s Firebase servers. That means only usage data is collected, no personally identifiable information. Then we can use Firebase Analytics and/or a similar platform to create reports of how our App being used. For example, a percentage of users that use certain features, or most popular Android and/or iOS versions and screen sizes among our users. We use these reports to understand how to spend our development resources more efficiently and make our Apps better. Note that we might share these reports with third parties. To learn more, check out Google’s privacy policy.


We use ads to keep PRAELUDIUM & CODEX free, except for our Gratitude Package, which is a free choice package and delivers extra futures. All ads in our PRAELUDIUM & CODEX Apps are served by Google’s AdMob or Unity Ads networks. AdMob and Unity Ads may use and collect anonymous data about your interests to customize advertising in our Apps and in other sites and apps. To do that AdMob and Unity Ads use unique user-resettable Advertising ID, provided by Google Play and/or iOS App Store services. Interest and location data may be linked to your device but is not linked to your identity. To learn more about AdMob and Unity Ads privacy policies and opt-out choices, check out Google’s and Unity’s privacy policies.


We will post any privacy policy changes on this page and, if the changes are significant, we will provide a more prominent notice. If you have any questions or concerns about our privacy policies, please write to us.
